How do I make Acrobat 11 append new scans automatic

Hi,

I like the new Acrobat 11 -

but it bugs the sense out of me,

that I have to check that radio box every time to append to the currently

open file (the one I am scanning from within).

Is there a default setting somewhere,

where I can tell Acrobat to always append to the open document?

Thanks,

Wil
